To all wiz/m t may concern." f i y Be it/ known tha-t- I, WILLIAM' F;HIM- siding at Syracuse, in the'county of Onon# daga and State ofNewYork, have invented certain new and` useful improvements in Ball-FeedingVacuum Lubricators, of which the following is a specification.

This invention relates to improvements in lubricators of theballfeeding-vacuum type.V

In lubricators of this typerthe rateof feed of the lubricant depends.upon the rate of rotation of the spring pressed lubricant feeding ballby the shaft'or spindle beingl'ubricated and upon the distance that theball is supported ofi ofV its seatV by the shaft or spin.- dle. In thepresent embodiments of. this or spindle is variable 'and as aconsequence. it

isV necessary Vto adjust a part or parts of the lubricator before itsyapplication to the bear# ing *or adjust. the lubricator on the bearingwith respect to the shaft or spindle in order Vto insure the supportingofthe ball off of its seatv by the shaft or spindle the dis-l tancenecessary to bring about the feed vof the lubricant atithe rate desired.To accom# plis'h this end is a difficult task and requires considerabletime, and mistakes are frequentlv made. which result in the engagementofthe tube in which the. ball is mounted vwith'the shaft or spindle'.Vfhen this oc# curs the lubricant will' not feed at the desired rate.and the Vlubricator. will soon *be Acome unfit for use owing to thewearingV away and the consequent enlargement'of the Hdiameter of theballseat.

sion of a lubricator wherein the 'ba-llshallbe vout` adjusting thelubricatorton-the' bearing withV respect to vtli'eshaft or spindle butonv the'niere application of the lubricator-to the bearing.

Anotherobject'of the'invention isfthe provision of a lubricator ofsuchconstructionasv to render it impossible' forthe :ball carrying tubeto engage theshaft orspindle.

A further object of the invention" is the" provision of a lubricatorwhich'shall be wherein tion of the lu-bricator,` i
